How to remember and reestablish the last currentIndex position of each ListElement?

Even tough I understand what you say and the philosophy behind it, my coding knowledge is too limited to create the code. My skill can only try and customize an existing code based on examples.

Right, that's one of the reasons I suggested the simpler approach.

Creating a custom component in QML is very easy.
Basically you just copy part of the code you have to a new QML file for which you use a filename that matches the name of how you want to call your component in the QML file using it.

E.g. your code conceptually looks like this

import QtQuick 2.4
 
Item {
    ListModel {
    }
 
    PathView {
        ....
    }
}

import QtQuick 2.4

Item {
    ListModel {
    }

    PathView {
        ....
    }
}

To copy to clipboard, switch view to plain text mode 

You then copy all code of that PathView section to a new file along side the original file, e.g. GameListView.qml

import QtQuick 2.4
 
PathView {
    ....
}

import QtQuick 2.4

PathView {
    ....
}

To copy to clipboard, switch view to plain text mode 

The original file can then be changed to

import QtQuick 2.4
 
Item {
    ListModel {
    }
 
    GameListView {
    }
}

import QtQuick 2.4

Item {
    ListModel {
    }

    GameListView {
    }
}

To copy to clipboard, switch view to plain text mode 

That does not work at this point because you have been referencing the list model inside the PathView.
But in fact you only needed the directory. so you add a property for that in GameListView.qml

PathView {
    property string directory
 
    ....
 
    FolderListModel {
         id: gameListModel
         nameFilters: ["*.png"]
         folder: parent.directory
   }
}

PathView {
    property string directory

    ....

    FolderListModel {
         id: gameListModel
         nameFilters: ["*.png"]
         folder: parent.directory
   }
}

To copy to clipboard, switch view to plain text mode 

You can then use multiple GameListView instances

Item {
    property int currentSubType: 0
 
    GameListView {
        visible: parent.currentSubType === 0
        directory: subTypeModel.get(0).path;
    }
    GameListView {
        visible: parent.currentSubType === 1
        directory: subTypeModel.get(1).path;
    }
}

Item {
    property int currentSubType: 0

    GameListView {
        visible: parent.currentSubType === 0
        directory: subTypeModel.get(0).path;
    }
    GameListView {
        visible: parent.currentSubType === 1
        directory: subTypeModel.get(1).path;
    }
}

To copy to clipboard, switch view to plain text mode
